Nietzsche is considered one of the most controversial philosophers of the modern age. His writings signalled a major turn in the history of Western philosophy and his influence is so profound that today not even the casual reader can ignore his life and ideas. In his book, Safranski positions the details of Nietzsche's unhappy life within the larger context of his thought. He talks about Nietzsche's boyhood obsession with music, his time in the army, his friendship with Wagner, his unrequited love for Lou Andreas Salome, quoting diaries, letters, and discarded writings - each of which reveal a different side of this enigmatic figure.
